SolRoNow calculate how dense earth would need to be to hold Jupiter in orbit.

And the tides.

And how long it would block out the sun during an earth orbit

And find out of tidal 'kneading' would melt our planet

Show all work.

(Also guessing the earth would be -inside- Jupiter, if Jupiter were at the distance of the moon)

BortWhy guess? Google for "Jupiter diameter". Then bear in mind the moon is almost 239,000 miles away from us.

BortAlso, about "hold Jupiter in orbit": the earth wouldn't hold Jupiter in orbit any more than the earth holds the moon in orbit. Both the earth and the moon (or hypothetically Jupiter) orbit the center of mass between them, which happens to be closer to the more massive body. So the earth would be more like a moon to Jupiter.

Albuquerque HalseyThis video is misleading. The point of view is too zoomed in. I can't find it, but someone did a mockup of all the planets at the moons distance, and Jupiter would be large in the sky, but still small enough to be blocked by holding you hands together, palms out in front of you at arm's length.

Albuquerque HalseyOK, I looked it up. The planet Jupiter would cover 20 degrees across the sky. Now, stretch out your arm and make a fist, and look at it with one eye closed. That's 10 degrees of vision it covers (including your thumb) and you can test this by 'stacking' your fists and see that it's 90 degrees from horizon to the zenith (highest point in the sky) So, if you put both of your fists together at arm's length (duh) that's how big Jupiter would look.
